nice to see such a dynamic project. I got some issues, though. Since 2.5 got this message error (ubuntu 12.04 64x)....never had any befor...maybe it could help debugging...this happens when I lounch ums from UMS.sh:

awesome! looking forward to testing this out. I just installed 2.4.2 the other day, but had bad A/V sync issues. I did some searching and found that FFmpeg is better to use than MEncoder? I'm hoping 2.5 does the trick. Thanks!
